Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts supply device, and more particularly to a transfer parts feeder supply device capable of supplying and aligning a wide variety of parts more reliably.

[0002]

2. Description of the Related Art Conventionally, a work supply device (part feeder) used in an automatic assembly line or the like has an alignment function section for uniforming one product in accordance with the shape of each part to be supplied,
Only a single type of component could be supplied. Further, for different types of parts, the aligning function part such as the feeder ball is exchangeable, and there is a drawback that the exchange is time-consuming.

Therefore, in order to solve the above-mentioned drawbacks, in Japanese Patent Application No. 4-148638 filed by the applicant of the present application, a removable tray having a storage frame corresponding to the shape of the component is attached to the final portion of the ball track. The present invention proposes an invention in which a multi-product part can be supplied by replacing the removable tray.

[0004]

However, in the invention described in Japanese Patent Application No. 148638/1992, the feeder ball type random work supply device disclosed inevitably corrects the position and posture of the storage frame. However, there was a problem that the overflowed parts could not be reliably returned to the feeder ball only by the static circulation means of the attachment / detachment tray.

Therefore, the present invention was developed in view of the above problems in the prior art, and has an extremely simple structure.
An object of the present invention is to provide a transfer parts feeder supply device capable of surely returning an overflowed component on a storage frame of a removable tray into a feeder ball.

[0006]

DISCLOSURE OF THE INVENTION The present invention relates to a feeding parts feeder supply device for vibrating a feeder ball having a ball track on the inner peripheral edge thereof to convey the components in the feeder ball along the ball track. The set base is supported below the final end of the ball track so that the vibration of the feeder ball is propagated, and is rotatably supported by a drive mechanism, and a removable tray having a storage frame corresponding to the shape of the component is mounted on the set base. It is configured by placing.

[0007]

In the transfer parts feeder supply apparatus of the present invention having the above-mentioned structure, the parts in the feeder ball are conveyed on the ball track by vibration. Inside the feeder ball, a set base that is separately movable below the final end of the ball track is supported, and a removable tray having a storage frame according to the shape of the component is placed on the set base. . Moreover, since the detachable tray is fixed to the feeder ball so that the vibration of the feeder ball is propagated to the detachable tray, the parts conveyed on the ball track are conveyed and transferred by the vibration transmitted from the feeder ball to the detachable tray. By the action, it is aligned and set in the storage frame on the removable tray.

After a certain period of time, the parts which have not been corrected in position and posture in the storage frame and have overflowed are returned to the feeder ball again by driving the attachment / detachment tray by the drive mechanism. Then, the parts aligned and set in the storage frame are supplied to the next step such as an assembly step by a supply means such as a robot. Also,
When changing the type of the component, the removable tray placed on the set base is removed and replaced with a removable tray having a storage frame corresponding to another shape of the component.

Embodiment 1 FIGS. 1 to 4 show the present embodiment, FIG. 1 is a perspective view of an apparatus, FIG. 2 is a sectional view of the apparatus, and FIG. 3 is a perspective view of a state in which parts are supplied onto a removable tray and overflowed. Figure, Figure 4
[Fig. 3] is a perspective view of a state after exclusion of overflow. Reference numeral 1 denotes a parts feeder main body having a vibrating mechanism installed therein, and a feeder ball 3 is attached to an upper part of the parts feeder main body 1 via a vibration transmission member 2. A ball track 4, which is a component conveying path, is provided on the inner peripheral edge of the feeder ball 3 in a spiral shape from the bottom to the top of the feeder ball 3, and the final end thereof is located substantially toward the center of the feeder ball 3. It has a projecting shape.

Below the final end of the ball track 4, a set base 6 on which the removable tray 5 is placed is provided so as to be substantially at the center position of the feeder ball 3. On the set base 6, two positioning pins 7 for positioning the detachable tray 5 are set up diagonally, and two positioning holes 8 of the detachable tray 5 engaging with the positioning pins 7 allow the component a The attachment / detachment tray 5 having a large number of storage frames 9 (holes in the drawing) formed so as to store the component a according to the shape is placed. At this time, the final end of the ball track 4 is located in front of (on the left side in FIG. 2) the center of the upper surface of the removable tray 5.

Rotating shafts 11 are attached to the left and right sides of the set base 6 via connecting members 10 which are attached with connecting pins so that they can be rotationally driven and are integrally attached. One of the rotating shafts 11 (on the right side in FIG. 2) is attached to a holder 12 provided on the outer periphery of the feeder ball 3, and the tip of the holder 13 bent in a U-shape so as to pass above the peripheral edge of the feeder ball 3. It is rotatably supported via a bearing 14. The other side of the rotary shaft 11 (Fig. 2
The left side of FIG. 2) is connected via a joint 17 to an electromagnetic brake motor 16 attached to another holder 15 provided on the outer circumference of the feeder ball 3.

In the apparatus having the above structure, a large number of parts a (screws having a cross hole in the head) stored in the feeder ball 3 are moved along the ball track 4 by the vibration of the feeder ball 3 along the ball ball 4. Is transported above. Then, the part a drops from the final end of the ball track 4,
It is supplied to one side portion on the detachable tray 5 provided in the feeder ball 3 and dispersed on the detachable tray 5.

The attachment / detachment tray 5 is connected to the feeder ball 3 via the set base 6, the connecting member 10, the rotary shaft 11, the holders 12, 13, 15 and the joint 17, and the vibration of the feeder ball 3 is transmitted. . Due to the vibration of the attachment / detachment tray 5, the component a on the attachment / detachment tray 5 is recessed into the storage frame 9 and aligned and set, and the position and posture of the component a are corrected.

After a certain period of time has passed since the component a began to drop onto the removable tray 5, the component a is stored in the storage frame 9 for a certain period of time.
Is determined by measurement in advance), and as shown in FIG. 3, the part a left on the removable tray 5 without being aligned is set to the electromagnetic brake motor 16
Is oscillated, the detachable tray 5 is tilted to drop the component a from the detachable tray 5, and the component a is moved to the feeder ball 3
I will return it to you.

Then, as shown in FIG. 4, the parts a which are orderly aligned and set in the storage frame 9 are detected by the supply means (handling claw) of the robot (not shown) by the sensor provided in the robot. Part a while checking
Are picked up one by one and supplied to the next process such as an assembly process. When the type of the component a is changed, the detachable tray 5 having the storage frame 9 corresponding to the component shape is exchanged, and the component a in the feeder ball 3 is also exchanged.

According to this embodiment, the parts that have overflowed without being corrected in position and orientation in the storage frame 9 of the removable tray 5 are reliably removed into the feeder ball 3, and the parts are neatly aligned and set in the storage frame 9. It is only a, and the efficiency of productivity can be improved. In addition, when supplying a different type of component different in shape, size, etc. from the component a, simply replace the component a in the feeder ball 3 with a new component by replacing it with a removable tray having a storage frame according to the component shape. Therefore, it is possible to construct a flexible assembly system that is easy to handle, has high versatility, and has a high degree of freedom in the parts supply section that requires versatility.
